To all whom 'it may concern:

Be it known that I, ARTHUR H. WRIGHT, a

of Minnesota, have invented ainew and useful Automobile, of which the following isa.

specification. My invention relates to improvements in vehicles of all classes, and especially to automobiles.

The object of this'invention is to provide easy running, durable and efficient vehicles of the class-mentioned, and also to provide means that will dispense with `pneumatic tires and springs-in automobiles and similar vehicles. l In the drawings, Figure 1 is a sectional side elevation on the line a-a of Fig. 2 and shows an automobile with my ynew mechanism aplied thereto. Fig. 2 is a top or plan view of `ig. 1 but with the body or latform of theV car shown in dotted lines. ig. 3 is a front elevation with some parts in section. Fig. 4 is a top view and Flg. 5 a sideview ofI the frame-supporting-journals used in connection with my improvements. Fig.'6 is a sectional detail view of a fraction of the fifth-wheel and supporting sockets which comprise lpart of my lnvention. j

Referring to the drawing by reference numerals, 1 designates the. body of an autoniobile of any type, this body is supported by the upperl rings of two fifth-whee 2-3 (as vbest shown in Fig. 3); the upper ring 2, of

each fifth-wheel being secured to thebody or pofted by the globular heads 5 of plungers 6 mserted downwardly into cylinders 7, having each a side arm 8 secured by bolts 9 to longifv 'tudinal sup ortin bars 10, Whose ends are provided wlth dis -shaped heads. 11 resting 1n sockets 12 in clips 13, pivoted at 14 to pendants or hangers 15, depending from fou'r axles 16, 16, 16", and 16?, the ends ofwhich are supported by eight groundwheels 17, and 17, o -'which onl the two rear ones, 17, are

l l fixed on the sha t and serve as drivers when reservoir (not shown) t their axle is revolved by any mechanism and motor (not shown) the other six wheels are journaled on the axles. l

By any suitable pumpling device and an air e engine or motor of the automobile keeps'the cylinders 7 at all times sup lied with com ressed air, which s upports't ev plungers an by them the body cushioned manner that no springs or pneumatic tires are necessary. f

` In further explaining the construction, it will 'be seen that the two rear axles, together with 4the supporting bars 10 between them,

and 16a and their bars 10 form a front truck. Each truck sup orts one of the fifth-wheels,-

vided with joints 18, .and thefskeins of leach axle provided with rocker arms 19, connected together by a transverse bar 20, and one of them by a link 21. to de ending rocker arms 22 and 22X of a rock sha t 23, rocked in bearings 24 by a toothed segment 25 fixed on Ithe shaft 'and engaged by a worm screw .26 turned bythe usual steering wheel27.

21 by a ball-and-socket joint -28:, normally ina central )osition below the frontv fifthwheel, and t e .rocker arm 22X is likewise connected in central osition below the rear fifth-wheel, by a ba -and-socket joint 28X to a link 29, which is pivoted to one end of a beam-lever 30,' fulcrumed at 31 to the lower ring of the fifth-wheel and has its other end ivoted to the inner endof the link 21, said earn lever being necessary to cause the rear truck' to turn to the o posite side from that of the-front truck'andp ing easy and quick.

. The cylindrical or disk-like heads .11 at the ends of the su porting bars 10, and the joints 14,- are` to allow free motion ofthe parts when the wheels run and jump .o'n'uneven ground. r

In Fig. 5 isshown a pin 35 for kee ing the end ofA the bar down in the soclliet. In said view it' will also be understood that the flat ends or necks of the bars 10 are guided lloosely inthe vertical slots. 12 so as to limit the rockingl motion of the bars.

lower of the fthewheel, and provided with a cap 33 secured by bolts 34 so as to be se arable.

aving thus described my invention, what I claim is:-

. 1. In an automobile, the combination The .rocker arm 22 is connected to the link.l

The ball-shaped form of the heads 5 of the of the vehicle with all its contents, in such a form a rear truck while the two front axles l1 6 i 65.l and is steered y having its front axle prothus' make the` steerwith a front and rear Wheel-supported truck, of upright cylinders'carried thereby, pistons or plungers in the cylinders, iifth-Wh-eels sup orted upon the plungers and sup orting thelbody ofthe vehicle, said plungersjlhaving at their upper endsball-shaped heads embraced by sockets formed on the lower rings of the fifth-Wheels.

2. In an automobile, the combination with a front and rear Wheel-supported truck,

of upright cylinders carried thereby, pistons or plungers in the cylinders, fifth-wheels supported u on the lungers and su porting the body o the ve `cle, said trucls each formed with two axles and four supporting Wheels thereon and two longitudinal frame bars, each su porting one of the cyl inders, hangers on he axles, elevises pivoted to thev hangers and having sockets With being' vvertical side slots, said supporting bars having at their ends heads resting in said sockets, and near the heads flat portions loosely guided in the slots for the purpose set forth.

3. In an automobile, the combination with a front and rear wheel-supported truck, of u right cylinders carried thereby, pistons or p ungers in the cylinders, fifth-wheels supported upon the plungers and su porting the body of the vehicle, and means iior steering the two trucks simultaneously in opposite directions.

In testimony whereof I affix my signature, in presence of two witnesses.
